If there's a contact number in the text then try calling that - if someone's transposed a number or someone else has put a mobile number into the system wrong then the messages might be important for the person they're intended for- if you can give the people/agency who called the heads up that they've got the number wrong hopefully they can get the right number so that the person they're notifying can be contacted.

Oh. Actually soon after I got a call for someone professional wanting to speak to a therese though they didn't identify themselves. Is bet that was the call and is definately wrong no. Very distracted today...
